To aZZ whom/it may concern.- v Be it known that I, ALFRED H. CROOKFORD, a citizen of the United States, residing at Barrison, in the county of Hudson and State of.

New: Jersey, have invented certain new and useful Improvements in Water Heaters and Purifiers and Boiler-Cleaners; andI do hereby declare the following to be a full, clear, and exact description of th'einvention, such as [0 will enable others skilled in the'art to which it appertains to makeand use the same, reference being had toithe accompanying drawings,

and to letters of reference marked thereon, which form apart of vthis specification.

The purpose of this invention is to provide a system of water-purification whereby the organic and inorganic matter held in solution in the water may be removed, leaving the wa ter free from any impurities that tend .to renz .der the same unfit'for either manufacturing or domestic uses.

One of the uses to which my improvedsystem'ajnd apparatus is intended to be applied is that ofa combined water heater and purifier and a boiler-cleaner', which is illustrated in the accompanying drawings, in which- 7 Figure 1 is a sectional view of my improved apparatus, showingthe relation thereof to a stationary boiler. Fig; 2 is a side elevation of a locomotive having the cleaning and purlfying attachment arranged thereon. I Fig. '3 is a view illustrating a particular arrangement of my apparatus attached to aboiler. is a top view of the water-tank. Fig. 5 is a 5 sectional view of a filtering arrangement on the end of a pipe within the tank. Figs. 6 and 7 are plan views of Skimmers adapted to In said views similar letters of'refe rcnee are 40. used to indicate corresponding parts.

A in.'the abovedescribed, views indicates the tank in which the soluble matterin the wateris separated therefrom and the .water purified, andals'o in which the feed-water is.

5- hea'ted when the apparatus is used as a coinbined waterheater and boiler-cleaner, and B is the boiler,with which said tank is adaptedto be connected by suitable pipes. Extending from saidtauk are pipesa a, through which the water passes to and from the-tank and boiler, the pipe a, which conducts the water temperature; of thewater is increased, as the tank and boileiyand also enabling theta-11k to Fig. 4

purposes-as for drinking-water+-the pum p 'fiOlll the boiler to the tank, entering the top ;ofsaid tank and extending down within the {same to or toward the bottom thereof, as shown in Fig. '1, while the pipe a, through which the water flfows from the tank to the boiler,enters or opene into the tank, so as to draw ofl'the. w'at'erfrem the top ofthe water-coluin n therein. 1 The pipe a, asgindicated in Fig. 1, is ar-' ranged w'ithiu' the'tank,extending from the top ol'ithe interior thereof down through the same and out throughjthh side, whereby the water is-drawni'rom the top of the watercolunin, and in passing dowlu through said pipe the 6. lower end ofthe pipe a. comes in direct. eon- J tact and is immersed in the hot water and steam, which is conducted, directly from the boiler by the pipe a down into the bottom of the tank and rises up within'the s dicated by the arrow'sin" Fig. 1. I

In either o}? the pipcsconneetin .the boiler and tank is arranged a pump, 0, which provides a positive means for causing and maintaining the'flow of thefiwater to and from the ame, as iu- 7o be placed in any desired'pos'itiou or at any distance in relation .to theboiler without alleet ing the circulation of the water. Further 1 more, when the water is purified in the tank by'iiltration, the pump'la'ets more powerfully to draw the water through the filtering mate .rial, and thus greatly facilitatesithe cleaning and purification of the water, and also when the apparatus isiuscd fordomestieor'ior'other readily forces the water from thetank to the height or place desired.

\Vithin the tank is'ar-rangcd a filter, which, as illustrated in tiae drawings, consists of two perforated plates-dd, between which the filtering material, (6., is placed, the lower plate resting on a ring, a", cast on orseeured to the walls of the tank, andto said ring the filter is secured by bolts or in anysuitable manner. The pipes a and a' extend through said .lilter, so that it does not interfere with the nermal purpose of such arrangement, and when the lieed-wateris forced or injected into the tank instead of into the boilcror into the pipe lead up: ing from the boiler; to the, tank; as dotted 'at' a, Fig. 1, the feedepipe e also extends down through the filter when the said pipe enters thetop of the tank, as indicated. Thus, the dirty water from the boiler and feed is thrown into the bottom oi the tank beneath the filter.

When the tank is intended to be used as a simple boiler-cleaner, removing the soluble matter in the water bythc gravitation or procipitation of the same down into the silt-receptacle a and drawing oh the clear water fro m the top of the water-column, the feed-water,

pipe e is omitted and the feed-water injected into the boiler in the usual manner; but when the apparatus is designed to act as a waterheater in addition to its function as a silt-separator or boiler-cleaner the feed-water in in jected into the'bottom of the tank, preferably through a pipe leading down within the same,

thus throwing the dirty water down into the bottom of said tank and permitting the sediment therein to gravitate into the receptacle a, similar to the method of introducingthe water from the boiler, the soluble matter in both cases having an opportunity to settlev into the tank.

Instead of inserting adlter in the tank, extending from side to side thereof}; a strainer, a, may be arranged upon the cadet the pipe a, as in Figs. 1 and 5, and may be filled with filtering material, as indicated, or; both of said filtering devices maybe used together.

The pipe (1, which conducts the water from the boiler to the tank, is connected with two pipes, a. and a, one of which, a, is provided with a broadened end or skimmer, a',which'is formed as shown in Figs. 1 and t or as in Fig. 7, and is placed in the boiler oni'thc water-line to take the scum and foreign matter which rises to and floats on the surface of the water,

. water at the water-line into the pipe a, and

thence into the tank, while the;pi pes a'a? conduct the water from the bottom of the boiler into said pipe a and the tank; Thus the wamy improved apparatus on a'loeomotive, in

ter from every part of the boiler is drawn into thetank, and any settling cr -accumulation of the sediment on the boiler-sheets is prevented. Valves 0 v are provided in the pipes a and a to control the current of water flowing from the boiler to the tank, being allowed to pass .through either ofthe pipes 42 or a, or both.

As illustrated in Fig. 1, the pipe a is connected with the pump, and extending bevond causing the circulation of the water.

the same into the botlorn of the rear of" the boiler is a pipe, a, while the pipe a", which In'said i es a and a" are valves oand '0 whichcontrol the admission of the water from thetank to the boiler throughsaid pipes. When the water is allowed to'jiow through the coil a", it passes through the tire, and, being .rapidly turned into steam, accelerates the flow of the current and assists the pump in This arrangement of the pipc leading from the tank to the boiler is of special advantage when used as indicated in Fig. 3, the pump being dis- When thus conpensed with in this case. structed, the tank is placed preferably above the boiler or the water-line therein, and the gravity of the water in the tank, assisted by the steam generated in the boiler, causes a' displacement of the water and results in a cur-v rent passing from the boiler to thetank and back from the tank to the boiler, as, indicated by the arrows in Fig. 3. The pipes leading from thetank to the boiler when thus arranged may also enter the rear of the boiler, as indicated in Fig. 3, and in'said pipes valves o o are provided to control the direction of the flow of. the currents of water.

Another arrangement of the tank with the coil beneath the boiler may be used, in which the tank is placed at the rear of and below or on a line with the boiler and the pipe a,which conducts the water from the boiler to the tank, 7

to communicate with the pipe a between the pump and the boiler, and through said pipe 7 the purified water from the tank is pumped or other purposes. When thusused, the flow to any desired place or reservoir for drinking of the water from theboiler to the tank'and from the tank to the boiler is out oif by closing the valves 12 and v and o, and the cold feed-water is drawn from the tank into the pipe f.

In Fig. 55 is illustrated an arrangement of which the same arrangements of the pipes as hereinbeiore described in relation to a stationary boiler may be used. The pump preferab ly used in this relation is a "horizontal pump, which is worked from the valve-rod of the engine through a lever, g, or in any other suitable manner.
